WARNING: services not running

MicCo · Aug 17, 2006

Hello,

We at MicCo WebDesign are testing an server with ISPConfig at an Debian Sarge release.

We are reciving this warning message every 30 min.:

WARNING: service not running (server: epsilon.eurohost.dk, port: 443)!

Any one knows what to do, due to that fact that we can't find any documentation for solving the problem.

is there an installed firewall on your linux box? kindly disable it and use the ispconfig firewall instead.

you can activate the firewall service of ispconfig under management->server->services.

The server are setup via the "The Perfect Setup - Debian Sarge (3.1)", so no other firewall, only the once in ISPConfig are used.

If you dont use IPv6, please try to comment out the line:

::1 ip6-localhost ip6-loopback

in /etc/hosts

and restart the services mentioned as not running.

We allready have done that, rebooted the system, twice.

Hmmm. what then when it's rearly not running ?

You can stop the emails by removing the systemcheck script from your root crontab.

I really dont know why your server is not able to resolve localhost to the IP 127.0.0.1
